One way of comparison shopping for fertilizer is to compare the cost per pound of primary nutrients in the various products.

Add the nitrogen, phosphorus and potassium percentages; multiply by the net weight of the package to approximate the pounds of nutrients contained.

A higher analysis fertilizer such as will probably cost more but will cover more area than a lower analysis. The exception of course is if a fertilizer also contains a weed killer or insecticide, which might injure certain plants.

Nutrient Needs of Plants There are 16 nutrient elements that are essential for the growth and reproduction of plants. Fertilizer Types Fertilizers may be divided into two broad groups: organic and inorganic, or chemical. Natural Organic Fertilizers: Cottonseed meal is a by-product of cotton manufacturing.

Cottonseed meal is frequently used for fertilizing acid-loving plants, such as azaleas, camellias and rhododendrons. Blood meal is dried, powdered blood collected from cattle slaughterhouses.

It is a rich source of nitrogen, and it supplies some of the essential micronutrients, including iron. Fish emulsion, a well-rounded fertilizer, is a partially decomposed blend of pulverized fish. The odor is intense but it dissipates within a day or two.

Manure is a complete fertilizer, but low in the amounts of nutrients it can supply. Manures are best used as soil conditioners instead of nutrient suppliers. Sewage sludge is a recycled product of municipal sewage treatment plants.

Two forms are commonly available, activated and composted. Activated sludge has higher concentrations of nutrients than composted sludge and is usually sold in a dry, granular form for use as a general purpose, long-lasting fertilizer. There is some question about the long-term effect of using sewage sludge products in the garden, particularly around edible crops.

Heavy metals, such as cadmium, are sometimes present in sludge, and may build up in the soil. Sludge use should be guided by results of chemical analyses of the sludge in question. Analysis or Fertilizer Grade Fertilizer ratios printed on the label indicate amounts of N-P-K, unless otherwise denoted.

Incorporation of materials with high amounts of carbon in relation to nitrogen, such as wood-based mulches and tree leaves, can result in nitrogen deficiencies in vegetable crops.

An additional 0. Incorporation of grass clippings and manures does not require additional nitrogen due to their higher nitrogen content. Phosphorus Phosphorus deficiencies in plants can develop in some Nebraska soils and are best identified with a soil test. Table V gives the suggested phosphorus rates based on a soil test.

Besides commercial phosphorus fertilizers, animal manures are a good source of this nutrient. Starter fertilizer — one high in phosphorus and applied in a band beside the row at planting — often stimulates early growth of certain crops or transplants e. Phosphorus is a non-mobile nutrient in the soil and should be applied prior to or at planting.

Phosphorus fertilizer can be broadcast on the soil and incorporated by tillage or it can be applied in a separate row beside the seed row at the time of planting. Row-applied fertilizer should not be placed in direct contact with the seed.

Table V. Guide for phosphorus fertilizer use on gardens. Other Nutrients Potassium is usually high in Nebraska soils, but occasionally a soil test may indicate a lower level.

The suggested potassium rate, based on soil test, is given in Table VI. Potassium should be applied prior to tillage. Sulfur deficiency can occur on very sandy, low organic matter soils, particularly in north central Nebraska.

A few vegetables, such as the cole crops cabbage, broccoli, etc. The application of organic materials, such as manure, will help correct the problem. Many fertilizers include small amounts of sulfur, which will be indicated on the fertilizer analysis found on the package label. These small amounts are often sufficient to overcome soil deficiencies.

Using ammonium sulfate as a source of nitrogen fertilizer supplies more than adequate amounts of sulfur. Table VI. Guide for potassium fertilizer use on gardens.

Interveinal yellowing of leaves — when the veins are green and the tissue between the veins is yellow — is symptomatic of iron chlorosis.

At a distance of several feet, chlorotic plants look very yellow. Lowering the pH in high lime soils can reduce problems with iron chlorosis, but the simplest approach may be to apply fertilizer containing iron. Several products are available.

Follow directions on the container for proper use. A manure application also can help supply iron. Zinc deficiency occasionally occurs when soils contain excess lime, are low in organic matter or have been eroded or recently disturbed.

Sweet corn and beans are the most likely crops to be affected. If zinc deficiency is suspected, the level of zinc in the soil can be determined by a soil test. If the zinc level is low, applying two to four ounces of zinc per 1, square feet will correct the problem. The application of barnyard manure also is helpful.

Zinc should be applied prior to tillage and can be applied as a foliar spray. To ensure an effective application, follow the directions on the container. Other nutrients calcium, magnesium, boron, chlorine, copper, manganese and molybdenum needed by plants and usually supplied by the soil are not known to be deficient in Nebraska soils and usually are of less concern in producing vegetable crops; however, low calcium transport in a plant is associated with blossom end rot of tomatoes.

Adjusting Fertilizer Based on Your Garden Area The lime, sulfur, and nutrient requirements presented in Tables I-VI are given as pounds per 1, sq ft.

Applying Materials When a Weight Scale Is Not Available It is often convenient to apply amendments and fertilizers based on a volume such as cups or ounces per garden area where a weight scale is not available. To determine the volume of material to apply, determine the following information: total volume cups, quarts, gallons, etc.

of material in the container, weight of material in the container listed on container , and total amount of amendment you want to apply over the garden area.

Use Equation 4 to determine the volume of material to apply to the garden area. For example, an individual needs to apply 3. From this information the individual calculates that approximately 5 cups of fertilizer are needed to apply 0.

Diagnosing nutrient deficiencies or excesses in fruits and vegetables is challenging. Many nutrient issues look alike, often more than one nutrient is involved, and the reasons for them can be highly variable.

N-P-K fertilizers with ratios of or are particularly well-suited for transplants and can be applied when plants are set in the ground. Foliar fertilizers may also be helpful in some cases, although most nutrient acquisition is through plant roots.

Foliar fertilization may be used to correct deficiencies during the growing season, to provide micronutrients such as zinc or iron when soil pH is greater than 7, or to supply nutrients such as potassium and phosphorus in cool spring soils, when plant roots absorb fewer nutrients.

Finally, remember to use fertilizer wisely and always follow label instructions. With the right amount of nutrients, however, your garden can thrive and provide pounds of produce for harvest. Rosen, C. Soil Resources and Fertilizers. In Weisenhorn, J. University of Minnesota Extension.

Now any grower can use the same organic fertilizers large-scale commercial farmers have come to depend on for over a decade! AgroThrive's manufacturing and bottling facility in California's Salinas Valley is operated on solar energy, furthering the company's commitment to sustainability.

The fertilizer we use inevitably comes into contact with the food that we eat, which is why it is critical that growers use a fertilizer that is completely pathogen free and safe for home use. Close menu.
